A rare presentation of ovarian fibrothecoma in a middle age female: case report

Fibromas/fibrothecomas are considered to be benign ovarian tumors. We describe a rare case of recurrent fibrothecoma with a clinically malignant course. A 42-year-old woman, with no family history of malignancy, operated multiple times for tumor that recurred three times within 4 years despite radical surgical removal. Initially, she presented with 9x7x10 cm right ovarian mass, frozen section was consistent with fibrothecoma and thus right salpingoopho-rectomy was performed. At the last two recurrences, she was found to have recurrent multiple abdomino-pelvic fibrothecomas and two long major operations were performed. This malignant behavior of a benign tumor is very rare. Further genetic analysis and immunohistochemistry studies are recommended to be conducted. Furthermore, new modalities of treatment should be considered, eg, high-intensity focused ultrasound and/or hormonal treatment.
